See page A-86 of our catalog and look at the picture in the bottom of the right hand column. That is what the seat assembly looks like. It would be part number A-321-BA. There are metal end pieces that attach to a piece of wood at the bottom and on the back. Then there is a piece of sheet metal that looks like 1/4 of a circle called the toe panel. It slips into the opening where the backrest board and the bottom board meet. The bottom board that comes in this kit is what attaches to your tracks. Your backrest seat spring attaches directly to the back board that is in the picture and it gets upholstered on the seat assembly. The cushion gets upholstered to another board which is part number AWD-1510-B. The upholstered cushion sets on top of the board that your seat tracks are bolted to. This is so you can take the cushion in/out to get access to the storage under the seat.
